How many waves @50GHz can Super-C provide?

Show Suggested Answer Hide Answer
Suggested Answer: C

TheSuper-C bandis an extension of the traditional C-band used in Dense Wavelength Division Multiplexing (DWDM) systems. It increases the number of available wavelengths by utilizing tighter channel spacing of50 GHz. Specifically, the Super-C band can support up to96 wavelengthsat 50 GHz spacing, compared to the standard 80 wavelengths in the conventional C-band.

This enhancement allows for higher spectral efficiency and increased capacity in optical transport networks, making it ideal for high-density traffic scenarios.

I thought it was 88, but I could be mixing it up with another frequency range we studied.

I have a vague memory of 120 being mentioned in class, but that seems a bit high for 50GHz.

I practiced a similar question, and I feel like the answer might be 96, but I can't recall the details.

I think I remember something about Super-C providing around 80 waves, but I'm not entirely sure.
